IMPROVEMENT IN CORN-PLANTERS..

Specification forming part of Letters Patent No. 169,721, dated November9, 1875; application filed 1 June 11, 1875.

To all whom it may concern: 7 I.

being had to the annexed drawings making a partof this specification,and to the lettersand figures of reference marked thereon.

Figure l ofthe drawings is a representation of a side elevation of mycorn-planter, and Fig. 2 is a plan view of the same. Figs. 3, 4, 5, 6,7, 8, 9, 10, 11, and 12 are detail views.

This invention has relation to machines which are designed for markingand checking the ground, dropping the corn, and covering the same; andthe nature of my invention consists in certain novel contrivanceshereinafter described, and specifically indicated in the claim.

In the annexed drawings, frame of the machine, which'is composed ofthree bars strongly secured together and rigidly attached in front to adraft-pole, B. C O designate transporting -wheels, which turn looselyaround an axle, O, and which are connected together by transverse barsa, suitably braced, and also by transverse check- A designates the rowmarkers 1; b. The markers b b make impressions in the surface of theground between the points where. the corn is dropped, which enables'theoperator to plant in perfect checkrows without previous marking. Theaxle O has one end bearing in the free end of a crankarm, 0, andtheother end bearing in one arm of an angular lever, 0, the other arm ofwhich latter is pivoted to a long lever, D. The lever c and the arm 0are rigidly secured to the axle O, and the wrist-pin of arm 0 and leverc are free to play up and down in slots formed in pendants d, which arevertically adjustable.

on the longitudinal side bars of frame A. This self-adjustment of thestuds or wristpins allows the markers to rise and descend, andaccommodate themselves to the inequali- E E designate arms, which aresecured to the axle Cl and extended back through vertically-oolong loopsat depending from the rear crossbar of frame A. The loops d affordguides for the arms E, and allow theirrear ends free vertical andendwise play, and on the arms E scrapers e are. secured, which keep theperipheriesof the transporting-wheels clear of adhering earth. Lever Dextends up alongside of an arc, F, and is curved overso as to form ahandle, which is in close relation to a drivers seat, S, and to thislever D another lever, D, is pivoted, which is acted'on by a spring, 8and constructed withastud, t, on its lower end, which is designed toenter one or the other of three vertical slots, t, made through the arcF, and to hold the parts in the desired position-at the same time allowfree vertical play. From the support on which the drivers seat ismounted to the front transverse portions of the frame A is a curvedapron or guard, A", which is designed for protecting the legs of thedriver, and at the lower end of this apron A is atreadle, G, which ispivoted to a plate on the draftpole B and passed through a slottedguide, 2, of this plate, and held up by a spring,'3. The rear end of thetreadle G lies upon the front cross-bar of a cranked lever, H, which isfree to oscillate in bearing-boxes g fixed to the side bars of frame A.The rear arms of the lever H are bent around the seed-tubes I, andpivoted to the short pitrnan-rods h, which connect said leverarms to therear arms of angular levers J, which latter are pressed down by coiledsprings 4. The lower or front arm of one of the levers J has anadjustable angular arm, 5, secured to it, which will be struck by theprojecting ends 6 of the straight bars a as the wheels 0 revolve. Thisraises the droppingslides 70 and discharges the corn. By raising the arm5 the wheels 6 will turn Without the projections 6 striking it, and theoperation of dropping may be performed by the driver pressing his footon the treadle G. The seed tubes I are rigidly secured to the side barsof the frame A, and at the upper ends of these tubes are hoppers I. Thedropping-slide of each tube is guided by means of a sheath, K,

which is held up against the back of the tube I by means .of aspring,sflandafixed bracket, L.-.. Inside of thetnbe I, vand secured to it, is

an inclinedguide, 7', which is directed downward and backward, and tothe front side of this guide a lipped striker, l, which is held in placeby a spring, m. The lower lipped end of the striker Z is pressed againstthe seedslide k, and regulates the discharge. of the grains of corn froman opening, n, through said slide. The size of this opening n can beincreased or diminished, as may be desired, by means of an adjustableslide, 0. On the lower end of each tube I is an opening-tooth,

N, which is beveled andcurved, asshown'in the drawings, for the purposeof moving freely through the soil and leaving a good drill in which todrop the corn. The corn is dropped throughthe heels of the teeth- N ateach ascent of the slides 70. In front of the teeth N .are curvedcolters P for cutting through the sods, and in rear of the teeth N arecoverers R,,which are appliedv to the lower ends of stocks R, and arevertically adjustable in the brackets. These-coverers have laterallyconcave bottoms, and they are tapered backward .so that their rear endsare. sma1lest.. They arc F, substantially as described.

2. The arms E E, attached to the axle O, and provided with scrapers e e,in combination with the guiding-loops (1 depending from the rearcross-bar of the frame A, substantially as described, and for thepurpose set forth.

In testimony. that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
